. To all whom t may concern:

Be it known thatfI, CLAUDE' STONE, a subject vof the King of Great Britain, residing at Sierra Madre, in the county ofLos Angeles and State of California, have invented certain new and useful Improvements in Cultivators, of which the following is a` specification. l I

This invention relates to improvements in cultivators and especially to 'cultivators designed for use in orchards or other places where the ground' is to be reached around trees and through vegetation of various kinds.

It is an object of the invention toprovide a cultivator of considerable width so that it may reach and cover the ground to a considerable distance beyond'vthefdraft team. The device is thus capable of reaching-beneath trees and the foliage of vegetation without the team striking the same.

It is -a futher object of-'the invention to provide supporting frames preferably mounted upon wheels, for controlling the depth to which the cultivating implements of the device will penetrate the soil.

It is a still further object'of the invention to provide a cultivator having a wide sweep, with supporting frames and hand operated controlling means whereby one portion of the cultivator may be caused to penetrate the ground to a less depth than another'pon tion of the cultivator, or all of the cultivating implements may be Vlifted lentirely out of ground engaging position, all under the control of the'operator orattendant.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

' In the accompanying drawing forming a part of this specification:

ground surface and is made to reach 4beyond the draft teamto suchy a degree, upon opposite .sides thereof. as to reachy beneathy trees and lother lvegetationwithout striking or injuring the foliage, blossoms or fruit there,- of. In the present improved form of the `cu'ltivator also, sectional controlling means is. provided whereby a portion, or all of the cultivating implements `mounted v upon the 'device may be caused to penetrate'. desired Vdepthsinthe soil according to the conditions thereof, orl may be lifted'en'tirely out of the v i soil when portions' vof the groundeare'not to bev disturbed or when the implement is to be moved overroads or from place to place.

The details land features of the invention ing, in which 6 indicates a tongueor draft bar, to which is secured transverse beams 7 and El).` The beams 7 and 8 maybemade of any desiredmaterial-but are usually made of channel liron for lightnessv and strength and the said vbeams extend transversely of the tonguef near the rear end thereof, being.

' will now-.be-morespecically described, ref- A i erence being had to the accompanying draw.-

secured thereto by any suitable fastening devices as 9. The said beams preferably eX- tend to.` equal distances upon opposite sides of the tongue Gand their outer ends are secured to and carried by side bars 10." The front beam 7 is bracedl with respect tothe tongue 6 by meansof. diagonal brace bars 12.

. The front and rear beams 7 and 8 are con# scopeof the inventionl and that theymaybe arranged closer 1 together or spaced farther apart as desired. Thecross barslljnot .only connect yand brace. the Abeams 7 and 8 but serve as suppOrts andcarrying means for the ground engaging implements employed.

As shown inthe Vdrawinff-,a cultivatinof im- 2D b i.

plement` is mounted upon eachof said cross bars land preferablyv consists of ,a stand- ;ard f 141 carrying 'a suitable -cultivator number thereof maybe employed within'the point l of any desired type. rlhe standards 14rare somewhat enlarged at their upper ends and are provided .vitli'pe'rfcrations 17 to ard .with respect to its bar 13 may be secured in'this manner and the cutting relation of the implement point l5 with respect to the soil may be thus altered. ln order to properly support the cultivator and to beable to control at will, the depth to which the implementswill cut the soil, the beam frame made up of the beams 7 and '8 and the side Vbars l0 are mounted upon wheels 20. Each of the wheels is j oiir'- naled upon the lower end of the'standard 22 by means of a `bolt 2l.y rEhe standards 22 extend upwardly from the wheels land across the en'ds of the bars LOto which they are pivotally connected by bolts 23. The'said standards also eXtend some distance above the bar and their upper ends are vpivoted to the ends of a connecting bar 2a.' 'By the movement of the ksaid bar 24 a parallel adjustment ofthe standards 22 is secured, as

o indicated in dotted lines in Fig. Sandthe position ofthe wheels is thus capable of alteration for varying the height of the culti.- vator points with respect to the ground.

The adjustable supporting means for the cultivator'fare preferably independently adjustable under the control of the operator. For this'purpose transverse shafts 25 and 26 are journaled in bearings 27 secured to cross bars 28. rhe said cross bars 28 are preferably secured at their ends to the beams 7 and 8 above the outermost and the yinnermost crossbars i8 as clearly'sliown in Fig. 2 and extend a suiiicient distance above the said beams lto not interfere with the adjustment of the implement standards below them, as will be clearly understood by reference'to Fig. 3 of therdrawing. The outer ends of the shafts and SIG are formed with crank portions 29, the material ofthe shafts being usually turned at right angles thereto and somewhat flattened for this purpose. The ends of these portions are connected by means of links 30 with the connecting bars 24 of the standards 22.

The inner ends of `the shafts Q5 and 26 are also turned upwardly at 31 and are bolted or otherwise firmly fastened to levers 3Q as'clearly shown lin Fig. Ll. vThe said levers are providedwith handles 38 at their upper ends and carry spring actuated latches Bil'which are arrangedv to engage the teeth 35 upon segmental rack bars' mounted adjacent t0 the levers 32. rllh'e said rack bars are secured to the tongue 6 near the opposite ledges thereof and suitable space. is Aleft between the levers 32 to permit of their operation independently of each other. rihe supporting `rstandardsmay thus be moved into various positions by the operation of their levers 32, to vary the height of the implement carrying beam frame while the cultivator isin operation. Y

The frontend of the tongue 6 is generally provided with any'suitable clevis 37 to which the draft team or means may be secured. llt is foundin practice that a span of horses connected by a double-tree rto the said clevis 37 is capable of operating arcultivator of Wide reach with great facility and the lends of the cnltivator will reach well beyond the Span so as to extend well beneath the branches and foliage of trees or other vegetation, so as to cultivate to points near their stems or trunks Without their being struck or injured by the team, Y rlhe independent adjustmentof the end supporting framesk by individual levers is admirably adapted'to a cultivator of such a broad. reach .and the implements carried thereby may beraised or lowered and adjusted to fit the different conditions of the soil or ground surfacevover which the ,device is passing, and without stopping the saine. When the standards, 22 are brought to their full height or vertical. positions, the cultivator will be so elevatedthat the implements will not engage the ground. This is needful when moving the mechanism from place to place and when traveling over roadways. Frquently also when cultivating around the trees of .all orchard lthatvloorders a road, one en dof .the cultivator will pass outwardly over such a road and the cultivator implements atthat en'd ofthe device may be lifted out of ground engaging position, vso las n otto injure the road surface, while the other end of the cultivator may be left in ground engaging position so asl to cultivate the soil between the trees and the road. The device is thus entirely under the control of the operator or atten lant and can be quickly adjusted by him to accommodate it to the. .varying conditions of the soiland locality.

What is claimed is: Y
